冰箱能耗標準-IEC 62552:2015發佈

20152月,國際電子電機委員會發佈了冰箱能耗標準-IEC 62552: 2015,這份標準替換了原來的IEC 62552: 2007版本,並進行了全新的編寫。標準一共劃分成如下三個部分。

·         第一部分:通用要求,包含範圍,定義,試驗室儀器和被測產品的安裝設置。

·         第二部分:性能要求

·         第三部分:能耗與容積

和原標準的主要區別如下:

1.  耗電量測試冷凍間室不再放置負載包,而改用銅質圓柱熱電偶來測量間室溫度,非冷凍間室中熱電偶的布點位置有重大變化

2.  試驗環境工況由25攝氏度變為在16攝氏度和32攝氏度分別進行試驗,最終進行加權計算年耗電量

3.  改變測試穩定判斷規則,測試週期從6小時到若干天不等;對化霜類型和化霜間隔有更細的分類和說明,總耗電量將化霜週期的能耗增量擴展到24小時

4.  內插法要求和計算方法有重大變化,增加了3點和多點內插的計算方法

5.  增加了放置負載的測試,並把這部分能耗也累計到最後的耗電量裡面

6.  對於防凝露加熱器和自動制冰機在能耗計算和測試時也做了明確的規定,這部分能耗也累計到最後的耗電量裡面

7.  總容積測量發生重大變化,不再需要測試毛容積

8.  貯藏溫度和冷凍能力測試布包方式發生重大變化,且試驗包種類只50mm*100mm*100mm這一種規格的

9.  增加零星級間室(0-STAR)和 食品室(Pantry)的溫度要求

10. 增加了酒櫃這種產品類型

11. 增加了冷藏室的製冷能力測試(cooling capacity test)

12. 增加了降溫測試(pull down test)

目前多個國家和地區(日本、新加坡、香港、馬來西亞、泰國、中國等)正在著手把這份標準應用于本國及地區作為最新的冰箱能耗測試方法,相信在不久的將來這份標準的應用面會逐步擴大。

 

 

IEC issued a new refrigerator energy consumption standard - IEC 62552:2015

In February 2015, IEC issued a new refrigerator energy consumption standard - IEC 62552:2015.This standard replaced IEC 62552:2007. The content of the standard has been significantly changed, and now it includes 3 parts.

·         Part 1: General requirements: scope, definitions, instrumentation, test room and set-up of products; 

·         Part 2: General performance requirements and methods for testing;

·         Part 3: Energy consumption and volume determination.

Significant technical changes with respect to IEC 62552:2007 include:

1.  For energy consumption measurements in Part 3, no thermal mass (test     packages) is used in any compartments and compartment temperatures are based on the average of air temperature sensors, the temperature sensor position have also been largely changed for unfrozen compartments.

2.  The energy consumption tests will be performed under two specified ambient temperatures (16°C and 32°C). The final annual energy consumption may be weighted mean of the measurements under these two temperatures.

3.  Change the stable condition requirements. Test period can vary from 6 hours to serval days. More detailed classification and explanation for defrost types and defrost periods have been added.

4.  For the energy consumption calculation, triangulation interpolation method and multi points (more than 3) interpolation method are added.

5.  A load processing efficiency test has been added in Part 3, and the energy consumption for this test is included in final total energy consumption.

6.  For anti-condensation heater and automatic ice-maker, specify the requirements in energy test, and the energy consumption of these parts may also be included into final total energy consumption.

7.  The method of measuring the storage volume has been largely changed, and need not measure the gross volume.

8.  The loading methods of test package and M package have been largely changed for storage temperature test and freezing capacity test, and only one size (50mm*100mm*100mm) is used.

9.  Add the temperature requirements for zero star compartment and pantry compartment.

10. Add a new type refrigerating appliance – wine storage appliance.

11. Add some new performance tests: cooling capacity test, pull down test.

Recently, many countries and areas (like Japan, Singapore, Hong Kong, Malaysia, Thailand, China, etc.) are adopting this new version as their national standard for the energy performance for refrigerating appliances, and it will be widely used for more countries and regions in near future.
